Grid line on resized image



Hi everyone,

    I tried to resize images generated from sensor and there are unobvious grid lines on the resized images. The locations of these lines are fixed and won't move with sensor images.

Following are the settings for resizer function - DRV_reszRun():

    [Input image]

    reszPrm.inType = DRV_DATA_FORMAT_RAW

    reszPrm.inStartX = 88

    reszPrm.inStartY = 66

    reszPrm.inWidth = 1872

    reszPrm.inHeight = 1404

    reszPrm.inOffsetH = 2048

    reszPrm.inOffsetV = 1536

    reszPrm.clkDivM = 10

    reszPrm.clkDivN = 50

    [Output image]

    reszOutPrm[0].outType = DRV_DATA_FORMAT_YUV420

    reszOutPrm[0].outWidth = 1024

    reszOutPrm[0].outHeight = 768

    reszOutPrm[0].outOffsetH = 1024

    reszOutPrm[0].outOffsetV = 768

    I tried to tune "clock divider(clkDivN)" and "gDRV_reszObj.ipipeifClk.pixelsPerLine" parameter in DRV_reszRun() function and there's no effect on these grid lines.

    How to resolve this problem?
